ALFRED F. SUMMERS AND CHAUNCEY NYE. OF PEORIA, ILLINOIS. Letters Patent No. 62,979, dated .March 19, 1867,

IMPROVED EGG DETECTOR.

ZBe itknown that we,ALFRED F. SUMMERS and CHAUNGEY NYE, of the city of Peoria, in the county of Peoria, and State of Illinois, have invented a new and improved mode of examining and detecting eggs, by

means of a machine which we call the Egg Detector; and we do hereby declare that the following is a. full, clear, and exact description of the construction and operation of the same, reference being bad to the drawings hereto annexed, and made part of this specification, in which Figure 1 is a perspective view; and

Figure 2 is a longitudinal elevation.

The nature of our invention consists in the construction of an apparatus or machine by means of which eggs may be subjected to the transmission of light through them, in such a manner that it can be determined by a visual examination whether they are good or bad.

We construct a dark chamber or box, A A, of convenient size and form, and paint the inner side of they same black, We make an eye-hole, D, in one end of the box, ,making the sameifiaring toward the inner side, so that the whole interior of the box may be seen through the eye-hole. We place-a reflector, C, in the box-in such aposition that the face of the same can be seen conveniently through the eye-hole D, holding the same in position by means of the ledge E or other support. We make a screen of proper size and form, of tin or any opaque material, and perforate it with round holes large enough to expose'the eggs through them when placed over the same. To make grooves in the sides of the box, upon the inner side. whereby the screen maybe held in a position parallel with the bottom of the box, and also .in a position slanting'downward toward the back of I the box, as represented in fig. 2, respectively by the lines marked B and F. When the screen is used in the set forth and described.

position indicated by F the reflector is removed and the machine i's used without it. When the screen is'used in the position indicated by 13 the reflector is kept in the position indicated by C.

In using the machine, we place the eggs in thciholcs of the screen, (a a, fig. 1,) and expose them to the light of the sun or to an artificial light of sufiieient brilliancy. When the screen is in the position indicated by H the images of the eggs (b b, fig. may be seen by applying the eye to the eye-hole. When' the screen is in the position indicated by F the eggs themselves may be seen, and the color or .clearness of them indicated with certainty, whether they are good or bad. I

What we claim-as our-invention, and desire to secure by Letters Patent, is- I The chamber A, provided with eye-hole D, the adjustable screen B provided with receptacles for the eggs,

reflector C, and ledge E, when all shall be constructed, combined, arranged, and operated-as and for the purpose ALFRED SUMMERS, OHAUNCEY NYE",
